[Service Launch] EC Mall “and ST” Implements SKYFLAG! Building a New User Experience and Revenue Model Focused on Maximizing LTV
Providing a More Rewarding Shopping Experience for Users via SKYFLAG, Serving as a Hook for F2 Conversion of New Customers and Ongoing Retention
Skyfall Inc. (Headquarters: Minato-ku, Tokyo; CEO: Tomokazu Hasegawa) is pleased to announce that its reward marketing platform, “SKYFLAG,” has been implemented by “and ST,” an EC mall operated by and ST Co., Ltd. (Headquarters: Shibuya-ku, Tokyo; CEO: Yuya Sakurai), which handles the mall and media business under and ST HD Co., Ltd.

Background of the Implementation
At “and ST,” emphasis has been placed on designing experiences that encourage continuous usage by providing added value beyond a standard EC shopping experience. At the same time, a key challenge was creating new revenue opportunities linked to service operations while simultaneously enhancing the user experience.
With this background, the company focused on “SKYFLAG” as a solution capable of generating results and expanding the scope of the user experience without compromising brand value. The fact that the platform can simultaneously improve the user experience and drive monetization aligned perfectly with the service policies of “and ST,” leading to this implementation.

About the Offers (Ads) Listed on “SKYFLAG”

SKYFLAG features a diverse range of offers (ads) across a wide array of genres, including gaming, lifestyle, and finance. Those offers’ completion difficulty levels are designed in incremental stages—ranging from easily achievable to long-term ones that award high rewards upon completion—to ensure that the diverse user base of “and ST” is able to choose offers best suited to them. This structure allows users to engage with offers (ads) based on their individual interests and usage styles.
Comment from Ryusuke Ichimura, Senior Manager of the Business Production Department at and ST Co., Ltd.
At “and ST”, we place great importance on evolving our EC application into an experience that users want to engage with daily, rather than letting it remain a mere place for shopping.
With that in mind, we determined that providing a way for our users to acquire points enjoyably and cost-effectively was essential, which led to our decision to implement the ‘SKYFLAG’ offerwall advertisement platform.
We feel a high affinity with our company’s strategic direction, particularly because the system allows users to voluntarily choose and participate in projects, thereby expanding the scope of the experience while delivering true value.
Moving forward, we will continue to improve our services from a user-centric standpoint, aiming to build a platform that enjoys even more sustained usage.
Comment from Yusuke Hosoda, Director of the Media Business Department at Skyfall Inc.
We are absolutely delighted to have ‘SKYFLAG’ implemented within ‘and ST.’ The service experienced a large number of users on a daily basis immediately after the implementation.
We feel that ‘SKYFLAG’ is contributing greatly to delivering brand-new value to the EC sector by optimizing shopping experience without hindering purchasing intent.
Furthermore, points acquired through ‘SKYFLAG’ are being utilized at a remarkably high rate. In addition to improving profitability, we are seeing a synergistic effect that has exceeded our initial expectations in terms of revitalizing the service as a whole. We will continue to collaborate closely to ensure we deliver experiences with even higher added value for all users.
